Dream, you have to make sure trayserver.exe and taskswitch.exe are not running at startup because they breake the Litestep systray. Both the programs I mentioned are part of DesktopX and from what I've read, will stay in your system even after an uninstall of DesktopX. You can either kill them at startup by opening your Windows Task Manager with "ctrl alt delete" find those programs in memory and kill them. Or search for those 2 programs on your drive, remove them and reboot. Though if you wish to keep DesktopX running on the other user profile, removeing them from the drive will breake DesktopX.

Personally I'd go for uninstall of DesktopX. Litestep is soo much better. :)
